Abstract

We investigate the impact of nonaxisymmetric structure on estimates of galaxy inclinations and position angles. A new minimization technique is used to obtain estimates of inclination and position angle from a global fit to either photometric or kinematic data. We discuss possible systematic uncertainties which are much larger than statistical uncertainties… (More)
